The　current　paper　experimentally　investigated　the　effect　of　different　kinds　re-dispersible　polymer　powers　(RPP)　on　cement-based　self-leveling　mortars.　The　construction　operation　of　mortar　and　its　mechanical　property　was　tested　in　accordance　with　the　standard　JC/T　981-2005.　Besides,　the　micro-structure　surface　of　self　leveling　mortar　was　characterized　by　means　of　SEM　to　reflect　the　microscopic　mechanism　of　the　performance.　The　results　showed　the　dispersible　polymer　powders　could　significantly　improve　performance　of　fluidity,　adhesion　property　and　abrasion　resistance　on　cement-based　self-leveling　mortar;　Meanwhile,　there　is　no　bad　impact　on　its　compressive　strength　and　flexural　strength.　This　study　has　guiding　significance　for　the　construction　and　application　of　cement　based　self-leveling　mortar.　©　2017　Trans　Tech　Publications.
